Beta 2 glycoprotein I (β2GPI) is a single chain 50 kDa highly glycosylated glycoprotein at an approximate concentration of 4 μM in cells. The abundance of this protein in plasma and its high state of preservation indicate the important role of this protein in mammalian. In addition, β2GPI has a particular structure in the fifth domain, and is categorized as the major antigen recognized by autoa...

Background: Celiac disease is a common autoimmune disorder that is diagnosed based on clinical case identification, serological screening, and duodenal histology. However, the existence of mild clinical forms, such as seronegative cases with patchy atrophy and potential celiac disease, can make it difficult to determine a definitive diagnosis. The seronegative patients with celiac disease can i...

Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaugh...

results a total of 205 blood samples obtained from diabetic patients (42 men and 163 women with age range 13 - 60 years) were examined for the presence of toxoplasma antibodies. among patients, 60 cases (29.3%) were seronegative and 145 patients (70.7%) were seropositive, included 53.145 (36.6%) (igg+, igm+) acute phase, 72.145 (49.6%) (igg+, igm-) chronic phase and 20.145 (13.8%) (igg-, igm+) ...

conclusions findings of this study demonstrate no significant difference between levels of h. pylori specific antibodies of iga, igg, anti-caga and the presence of pcos disorders, and also indicate that serologic testing is a sensitive method for the detection of h. pylori antibodies. the high prevalence of h. pylori positive antibody levels in both pcos and non-pcos patients can be probably as...

background because of the economic importance of the arab race horses and also the role of toxoplasma gondii and neospora spp. in abortion and reproductive failure of these animals, we decided to perform this study. objectives we designed this study to investigate the seroprevalence of anti-toxoplasma gondii and anti-neospora spp. antibodies in arab horses from 12 cities of khuzestan province i...
